vEHIcIiE TIRE.

Application led March 8,-1926. Serial No. 93,112.

I liner has .a tube therein by which said casing is inflated with compressed air to hold an inflated outer or tread casing on the tire These objects I accomplish with the device illustrated in the accompanying drawings in which similar letters and numerals of reference indicate like parts throughout the several views and as described in the specification forming a part of this application and pointed out in the appended claims.

In the drawings in which I have shown the preferred embodiment of my invention, Figure l is a'view in perspective cross section of the tire.D Figure 2 is a perspective cross sectionon line 2-2 of Fi re 3. Figure 3 is a .plan view of a portion of the inner tubel showingthe opening through which the air valve passes. Figure 4f is a. cross. section of the air valve vand the inner casing. Figure 5 is a cross section of the inner liner. Figure 6 is a cross section of the soft rubber filler. Figure 7 is a cross section of the outer casing, with the inner; liner and filler in place between them. Figure 8 is a crbss section of the inner casing. 1

In the said'` drawings the present invention is shown with the tread casing as A and thel tire rim as B. The valve lstem is shown as C and the nut to hold the same in vplace within the tire rim is shown as D. I

use an ordinary outer casing as my tread casing A, which is adapted for use on the tire rim B of thel vehicle wheel. On the innei` wall of said tread casing A I yprovide a long napped filler member 1, conforming to the shape of the interior of said tread casing except that its edges do not come together. On the inner walls of the casing A and of filler member 1 I provide inner lining F withits edges turned back, as shown at 4. To secure and seal the said tread casing A to the tire rim B I provide an inner casing E, having three wallsand formed into an annular form Awhich is practicall triangular in cross section when fully in ated, with the edges constructed of `fabric and rubber and positioned vcontiguous the edges of the inner lining portion F of the tread casing A, with the said sides 3 and 5 in contact with the portions 4 of said inner lining por-a t-ion F of thc tread casing. Vithin sind inner casing E is the inner liner portion 6, which is made of thin, flexible material. ',lhc said liner 6 is made of a flexible fabric cover on its outer face with soft rubber, and

with its edges adapted to overlap contiguous l the said rim B. The side walls of said liner portion 6 bear against the por-tions 4, 4 of the liner portion F when the tire is inflated.

fThc portions 3 and 5 of the edges of said inner Vcasing are also made of soft rubber to secure a better sealing of my tire when it is inflated. An air tube G is Aprovided for inflating the said inner casing, which tubeV is for most/of its length similar to a bicycle tube, and for the remaining portion is dividedinto two tubes, as sho-wn in Figures 2 and The hole formed between the two tubes is to let the air valve stem C for the outer casing A pass therethrough.

The assembling of-my device is as fol- Ilowsr-Within the convention outer casing I first place a long napped filler casing of gummy uncured rubber and to hold this to the inner face of the casing A I provide an inner liner F made of cured rubber, similar to the rubber in an inner tube. I then place the inner casingE within the outer casing and with the tapered edges 3 and-5 and the inner liner 6 'in 4close contact with the ends 4 of the liner F. The small inner tube G is placed within the inner casing E and inflated by air introduced through the air tube 'H, which is ofthe conventional type-*and is secured ,to and opens into saidtube Gr. The pressure of the air Within the inner tube G on the inner liner 6 will force thc .overlapping portions of the said liner 6 `the desired amount without any leakage therefrom and the face of the outer casing may .be punctured` by nails or other-sharp articles and th'e gum in the filler 1 willhll the puncture as soon as the object is with-I drawn, makin a puncture-proof tire and one which'wil not stoneebrmse or rim-cut. desn'ed amount of air can be placed A11 within the respective casings A and E.

Having thus described my invention I desire to secure by Letters Patent and claim l. A vehicle tire comprising an outer casing having a soft rubber filler and an inner liner cemented to form a casing; ianged edges on said inner liner; an inner casing concentric with said outer casing and carried therein; edges on said inner casing adapted to fill the space between the flanged edges of said inner liner and the main body of said liner; a soft rubber liner, a portion of which is cemented to the inner Wall of said inner casing', and having overlapping edges thereon.; an inner tube Within said inner casing; and means to inflate both of said easings.

2. A vehicle tire comprising an outer casing made by a filler member and a lining member cemented to each other and to the inner wail of said outer casing; an inner casing triangular in Cross section concentricaily carried in said outer easing; said inner casing consisting of a casing having soit rubber edges; a liner therein with overlapping edges; an inner tube carried in said last mentioned casing and having a divided portion to form a sealed slot transversely through said tube; and an air valve passed through said slot and through the overlapped edges of said liner and through said inger casing; and means to inflate said inner tu e.

3. A vehicle tire comprising any outer cas, ing which consists of a tread casing with a filler member and a lining member ce-v mented together; an inner easing carried within said outer casing, and wnlcn inner casing consists of a fabric casing having rubber edges; a liner within said inner casing; an inner tube carried Within the last mentionedcasing andy having a sealed transverse slot through said tube; and an air valve stem passed through said slot, and inner casing to inflate said outer casing.

In testimony whereof I have affixed my signature.
